Skarn deposits are abundant, variable, and economically important. They are a principal global source of tungsten, a major source of copper, and an important source of iron, molybdenum, zinc, and gold.
Skarn is an assemblage of dominantly calcium and magnesium silicates typically formed in carbonate-bearing rocks as a result of regional and thermal metamorphism, and by metasomatic replacement. Regional and stratiform metamorphic skarn deposits include, for example, skarn iron deposits that were derived from iron-rich sedimentary and volcanic rocks by recrystallization, isochemical meta-morphism, and bimetasomatism. Recrystallization, in particular, results in upgrading the quality of ore for concentration, beneficiation, and...

Geology of Canadian Mineral Deposit Types
This volume defines and summarizes in a comprehensive and systematic manner the essential characteristics of all economically significant types of Canadian mineral deposits. These summaries reflect the current understanding of mineral deposits and correspond closely to the definition of mineral-deposit types in common use. A large color section serves to illustrate details of some of these mineral deposits, and locations of all known deposits are presented on an oversize figure and are indexed in an appendix, as well. Like previous volumes of this type, this volume will be a long-standing premier reference for academia, industry, and government institutions alike.
